Description
C17200 Beryllium Copper Rod ASTM B196 — TF00 Age-Hardened Bar for High-Strength Industrial Applications
C17200 Beryllium Copper Rod ASTM B196 in TF00 temper is a precipitation-hardened copper alloy bar with 1.80-2.00% Beryllium that has a tensile strength of 1110-1320 MPa and a hardness of 36-42 HRC as received. Also known as Alloy 25 / CuBe2 / UNS C17200 / EN CW103C, it is manufactured to ASTM B196 and SAE J463 specifications. Available in diameters from 2 mm to 200 mm, this rod arrives ready for rapid machining with no post-delivery heat treatment required. ISO 9001:2015 certified and RoHS/REACH compliant, every batch is sent with an EN 10204 3.1 Mill Test Certificate (MTC). Dongguan Jiaye Dingsheng has been specialising in producing beryllium copper since 1997.
What Is C17200 Beryllium Copper Rod ASTM B196?
C17200 Beryllium Copper Rod ASTM B196, or Alloy 25, is the highest strength copper based alloy available for industrial use. The usual copper alloys are not mechanically strong enough for demanding applications, but high-strength steels have issues when electrical conductivity, magnetic neutrality or spark resistance is needed.
This alloy fills the void. It has the tensile strength of steel (up to 1320 MPa), the thermal conductivity of copper (105 W/m·K), and the electrical conductivity of copper (22–25% IACS). It is non-magnetic (permeability < 1.01) and non-sparking in the natural state.
TF00 signifies that the rod has been entirely solution-annealed and age-hardened at the manufacture. You get a part-ready bar, saving you time and heat treatment expenses.
Chemical Composition
| Element | Content |
|---|---|
| Beryllium (Be) | 1.80 – 2.00% |
| Cobalt + Nickel (Co+Ni) | Min. 0.20% |
| Copper (Cu) | Balance |
The Co+Ni additions control grain growth during precipitation hardening, producing a fine grain structure (typically ASTM grain size 5 or finer). This contributes directly to superior fatigue resistance and machinability.
